A fun little chemistry game for girls, Atom chain reaction illustrates in a fun way the minute chemical chain reaction happening all around us in every glass of water. The game is simple, before you is a plane of water molecules with oxygen in green and hydrogen in red. Just like in real chemistry the hydrogen atoms interact with each other, and when you click on one of the atoms it turns 90 degrees to the right, if one of its hydrogen atoms aligns with those of another atom's then that atom turns. This reaction can quickly spread across the entire boar for a neat effect. A custom chain reaction designer is also available.
